    <p>I currently have this code that I wrote up:</p> <pre><code>$username = $_POST['username']; $password = $_POST['password']; $rpassword = $_POST['rpassword']; $usrip = $_SERVER['REMOTE_ADDR']; $email = $_POST['email']; $errors = array(); $checkUsername = $odb -&gt; prepare("SELECT COUNT(*) FROM `users` WHERE `username` = :username"); $checkUsername -&gt; execute(array(':username' =&gt; $username)); $countUsername = $checkUsername -&gt; fetchColumn(0); if ($checkUsername != 0) { $errors['Username is already taken']; } </code></pre> <p>However it seems to just completely ignore this and even if the username is identical (capitals and such) it will still allow the user to register making 2 of the same users. My database looks like this:</p> <p><a href="http://puu.sh/1mTcZ/9b2ff3b68f44b4cc486beacc2d2b88fd" rel="nofollow">http://puu.sh/1mTcZ/9b2ff3b68f44b4cc486beacc2d2b88fd</a></p> <p>I cant seem to get this working at all. The database structure looks like this: refined (dbname) > users (table) > username (row)</p> <p>Any help is very much appreciated.</p> <p>Edit:</p> <p>After a few changes this is what I have, however I still seem to be having the same issues.</p> <pre><code>$checkUsername = $odb-&gt;prepare("SELECT COUNT(*) FROM `users` WHERE LOWER(`username`) = :username"); $checkUsername -&gt; execute(array(':username' =&gt; $username)); $countUsername = $checkUsername -&gt; fetchColumn(0); if ($checkUsername != 0) { $errors['Username is already taken']; } </code></pre> <p>The username row is also now utf8_general_ci</p>

    1. COYour IF statement evaluates ($checkUsername != 0). Shouldn't this be ($countUsername != 0) ?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
